Members of the Barry family say their great-grandmother died after she witnessed her grandson being bitten by a snake at Disney’s Animal Kingdom.

The 8-year-old boy was visiting the park in October 2014, from Alabama, when the family says the green and brown snake fell from a tree and bit the boy on the legs. The boy had some swelling, but was not seriously hurt. The family members said the great-grandmother, who was in her 90s, began to have difficulty breathing, and they left the park.
